San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
Why Won't The City Or County Animal Services Help Me With A Rat Infestation?
If you discover rats frequently in and around your home or see a lot of rat droppings, you may have a rat infestation. This clearly is awful news and for various reasons. Not only can rats bite on wires, wood, and even though dividers, causing immense damage to your home or business, but they also carry diseases. Despite general thinking, rats are not clean - they are perfect when kept as pets, however out in the wild, they can and will spread illnesses. What are your options with regards to a detected rat issue? Would it be advisable for you to contact the nearby animal control, deal with it yourself, or recruit an expert wildlife control service?
Will the city or county animal services help? The short answer is no. They are only liable for public spots. If your concern is with the surrounding area around your home, similar to a recreation center or abandoned public spaces that have become swarmed by rats, you may have a shot at getting them to help you out. However, if we're discussing your own property, which is private property that belongs to you, the local authorities have no business interfering. What's more, if they will, it is to advise you to deal with the infestation as it can spread, and depending on where you live, there may be local laws that can target you and force you to do something about it.
